i recently purchased a 2003 chevy 5.3l with 120,000 on it ready for a drop in for $750 an.d I'm searching for the best options for motor mounts. I haven't completely decided between a 4l60e or an nv3550 from a jeep. I would like to keep all my gauges so I know I need my mechanical transfer. but the adapter for the transfer to tranny cost as much as the engine. just to pricey so looking for theories on that as well. its going into a 1991 jeep wrangler s 2.5l ax5 thanks for advice in advance. I'm wanting to keep this to a budget and will be doing the labor myself.
